What makes the Earth’s atmosphere so special? What makes the atmospheres of other planets so special? Why are atmospheres so special anyway?
Why do we think the solar system might have another planet? Why do we think it doesn’t? How do test for something that’s too far away to see?
Why is the speed of light so important in physics? Why does the value not matter at all? And why does it have the speed that it does? I discuss these questions and more in today’s Ask a Spaceman!
How can a supernova become even more powerful? Why do we have such a hard time studying them, let alone defining them? What happens when you let a giant star unleash its full potential?
Part 8! How did String Theory get started? What has made the idea so popular over the decades? Can we ever truly have a theory of quantum gravity? What is supersymmetry, the landscape, and the AdS/CFT Correspondence? What do holograms have to do with this? How many dimensions do we live in? Why does String Theory have such a hard time making predictions? How are we supposed to judge a theory that isn’t done yet?
